Re: Test of gun.

1. Make the screen shake on the frame he shoots, just move everything to the right 10 pixels, then 3 pixels on the next frame.
2. Use a more realistic muzzleflash (gun-light thingy), one that is smaller.
3. Use a straight line to show the path of the bullet instead of a huge fan-shape.
4. Make his leg move like you did, but keep the foot in the same place.
